ADDING AND WRITING MACHINE.

Application filed January 24, 1903.

Louis, Missouri, have invented a new and useful Improvement in Adding and Writing- Machines, of Which the following is a specification.

This invention relates to adding and writing machines; and it consists of the novel construction, combination and arrangement of parts hereinafter shown, described and claimed.

One object of this invention is to produce an adding and Writing machine, comprising a word printing department, and m adding and recording department, having a common platen upon which commercial sheets of paper of any required width can be introduced and upon which joint written and arithmetical records, can be printed without previous adjustment of the two departments relative to each other, or intermediate connecting or actuating devices.

Another object is to produce a machine, of the class mentioned having registering devices connected (separably) with the totalizing wheels which are operated therebv and in which the carrying is accomplished by the movement of the registering devices, without intermediate actuating devices.

A further object is to produce an adding and writing machine having the type bars of the writing department arranged with a space wherein the adding-mechanism-tye move, to record in alinement with written records, produced by the writing department.

A further object is to provide a machine of the class mentioned having the recording devices of both departments arranged to print on the front of the platen to produce oint alined visible results. v

A stilhfurther object is to produce a machine of the class mentioned in which the ccoi'ding devices of the adding department are located within the machine and movable toward the printing point of the Writing type bars on the platen so that both departments will record along the same line when it is desired to obtain or produce a joint result, such as identified items.

Another object is to produce an integral adding and writing machine of compact and simplified construction adapted for use Specification of Letters Patent.

machine comprising a Patented Sept. 24, 1912.

Serial No. 140,390.

for either purpose at any time without previous adjustment, all the records beingmadeupon a common platen and visible to the operator as written.

Another object is to provide an adding machine comprising a series of type-carriers, a series of hammers for 'cotiperating with the type to produce type impressions, a releasable latch for holding each hammer in idle adjustment, a carriage whose opera- 55 tion is necessary before said-type-carriers 'and said hammers may be operated, and

means for releasing one hammer for each type-carrier operated while the remaining hammers remain latched.

Another object is to produce an adding machine comprising a platen arranged to hold paper, a series of type-carriers operable to record numbers on paper on said platen, a series of devices for. driving the type, which are carried by said type-carriers, toward said platen to record, a carriage whose operation is necessary before said type-carriers may be operated, and mechanism for operating all of said elements.

Another object is to produce an adding laterally-movable platen arranged to hold paper, a series of type-carriers, a series of movable type on each type-carrier, a series of drivers or hammers for driving the movable type toward the platen to record on said paper, adding mechanism operable to add the numbers recorded, means for moving the paper in line spacing in any position of the carriage, and 00 a carriage. whose operation is necessary before said type-carriers and said adding mechanism may be operated.

A further object is to produce an adding machine comprising listing and adding mechanism operable to list and add numbers, a laterally-movable paper carriage, automatic means for feeding the paper in line spacing in any position of the paper carriage as an incident to the listing of a number, and a carriage whose operation is necessary before any number may doe listed.

Other objects will a pear from the following description, an do not require specific mention, reference being made in the description to the accompanying drawings, in which- Figure 1 is a plan view of the machine, Fig. 2 is a sideelevation, Fig. 3 is a right side elevation with the case emoved.

Fig. 20 is a plan of the same mechanism. Fig. 21 shows the ribbon feed mechanism, located under the base of the machine. Fig. 22 is a sectional view taken on line dd of Fig. 21.

The case 1 is located on the base 2 and incloses the operative mechanism of both departments-the writing and adding. When the machine includes the typewriting mechanism the keys of the two departments preferably form separate groups for convenience and to avoid confusion to the operator though it will be apparent that the adding and listing mechanism, with the common or joint platen shown, orother suitable platen for supporting and feeding the paper, may be employed without being combined with the typewriting mechanism. In fact, such separate construction and use of the adding mechanism is contemplated, as well as in combination with the typewrit-ing mechanism. The key levers 3 of the adding dei partment are preferably grouped below those of the writing department and are spaced at convenient distances but converge centrally about midway of the front and rear of the machine and are' pivoted upon a com mon support 4 rearward from which they extend parallel as clearly shown in Fig. 6. Behind the pivot 4 the key levers are bent as shown so that their rear ends are in longitudinal alinement. All the key levers except the 9 have vertical projections 5 rigid with their rear ends the upper-extremities thereof being circularly alined.

See 3. A track consisting of two par.-

allel members 6, is supported transversely above the rear ends of the key bars 3. A frame or carriage, having a rear end plate and a front end plate 8, is supported upon said track by means of the rollers 9. The plate 8 extends a distance to the left of the carriage and carries a rack 10 and said rack is attached to the spring motor 11 whereby the entire carriage is drawn from right to left across the machine on the track 6.

A vertical shaft 12 is supported by the base 2 of the machine leftward from the rear ends of the key levers 3 and carries a gear wheel or segment 13 in mesh with the rack 10. See Figs. 6 and 9. Another segment 1st is mounted loosely on the shaft '12 below the segment 13 and meshes with a rack 15 on the bar 16 extending longitudinally toward the front and having its latter extremity pivoted to a link 17 suspended from same portion of the inner side frames 18, which uphold most of the adding mechanism and are secured rigidly to the base 2.

A segmental plate 19 is attached to the shaft 12 above the segment 14; and has integral therewith on its outer edge, a series of ten teeth or projections 20 which are approximately diamond shaped in cross section. See Fig. 9. A bar or escapement member 21 rests transversely upon the key levers 3 and is connected to the arms or links 22, the rear ends of which are pivoted upon a cross rod or shaft. 23. An arm or pro ection 24 is rigid with the left end of the member 21, and carries a depending hinged cscapement member 25 of known construction, which normally engages with the projections 20 on the segment 19. A projection 26 is rigid with the member 21 and engages on the opposite side of the tooth 20 from the member 25. by a key lever the member 25 is disengaged from the tooth 20 and the motor 11 draws the stop frame to the left until the projection 26 stops the movement by engagement with the next tooth 20. Then when the kev lever is released the lever 21 lowers to its normal position and disengages the projection 26 and again brings the member 25 into contact with the tooth 20. In this manner the escapement controlled by the key levers 3 governs the right to leftmovement' of the stop frameor carriage across the machine.

The frame or carriage which as above referred to is carried by the plates 7 and-8, consists of a series of a'rcuate plates or metallic strips 27, Figs. 10 and13 spaced atuniform distances and extending longitudinally in the machine. Eachplate carries nine vertically movable pins 28 arranged in transverse rows. In idle or normal osition the pins 28 on the plate 27 at the eft are immediately 0V0! the projections 5 on tlfe key levers 3, so that when any key lever, except When the bar 21 is raised the one representing 9, is struck one of pears.

the pins will be operated, the cross member 21 raised and the carriage moved one step leftward as above described, which results in the second longitudinal row of stops being brought over the projections 5. The nine pins 28 on each plate 27 represent the ten figures except the 9 for which no pin is provided, the key lever for that figure terminating below the cross member 21, which will be operated thereby in the same manner as by other keys. A special immovable part 29 is carried by the plate 8, said part being the 9 stop as hereinafter ap- The rear pin in each longitudinal row represents and the other figures are represented in order by these movable pins exwpt 9 which is provided for by till the special immovable part 29, as stated. These pins are held by pins 30 rigid with the plates 27 and extending through slots 31 in the pins and thereby allowing the latter to move when struck by a key rejection 5. Small springs may be provide to assist in retaining these pins in any position.

An arched member 32 Fig. 8 is secured to the parallel track bars 6 and is of sufficient height to allow the movable carriage to travel thereunder. A series of nine fingers or projections 33, one for each transverse row of pins 28, extend therefrom over the left side of the carriage, so that when the latter is restored to position the pins 28 will be forced down by passing under the fingers o 33, to their normal position.

A shaft 34 is supported by the frame of the machine, a sleeve 35 encircles the same and a series of gear sectors or racks 36 is pivctally mounted upon said sleeve. See Fig. 7. An arm 36 is rigid with each end of said sleeve, said arms projecting rearward and being connected by a rod 37. These gear sectors or racks are at sufficient height to permit the carriage to pass thereunder without obstruction, but each sector or rack has a downward projection 38 at its rear side which engages with the pins 28 as will be explained farther on. For each gear sector there is a corresponding type carrier 39 also supported on the sleeve 35 and the arcs of which are somewhat longer than the gear sectors in order to extend in front of the platen. sector there is an arm 40 aldngside of the corresponding type carrier in each of which is formed a slot 41 alongside of the arm 40. A pin or button 42 is secured to the end of the arm 40 and extends through the slot 41 thereby forming a loose connection between the racks and type carriage .ermitting the latter to have movement in ependent of the former for a short distance. This independent movement on the part of the type carriers, however, is limited by the length of'the slots 41 as is evident. Two

Rigid or integral with each gear depending arms 43 extend from the sleeve 35 and support a rod 44 against the front edges of all the sector arcs and thereby holding them all at the limit of their backward movement and clearly alined. The upper ends of the type sectors have arms 45 projccting rearwardly and connected by springs 46 with the gear carriers so that when they are all released the type sectors will be drawn forward independent of the gear sectors till the button 42 rests in the rear end of the slot 41. The arms 45 are also connected with the rod 37 so that when the sleeve 35 is turned to move the arms 36 downward the type sectors will be drawn go forward the rod 44 moving simultaneously. The front ends of the type carriers carry frames 47 within which the types 48 are located, being movable and held actuated outward by small springs and having their 35 printing faces inside the arc of the arcuate type-carriers. The gear sectors are held backward by a stop or retainer 49 supported by the movable carriage in front of the projcctions 38, and in alinement with the rear row of stops 28 which represent 0. When the carriage is at the right, which is its idle position, the stop 49 is in front of all the projections 38, but eachstop to the left releases one sector, so that when the sleeve 35 is turned the sectors not held by the stop 49 will be drawn forward by their springs to which reference has heretofore been made. A link 5d Fig. 3 connects one of the arms 36 with a segment 51 attached to the main 10o shaft 52.1ocated near the base of the machine. The link 50 is provided near its lower end with-a slot53 through which the connecting pivot screw extends and a spring 54 formsa yielding connection so that when the main shaft is turned the link will be moved without a jerk. This results in retation of the sleeve 35 and the rod '44 will be moved forward to release the sectors. A handle 55 is on the right end of the shaft 52, for operating purposes. -Strong springs 56 are provided to restore the shaft 52 and the type-carriers and racks to position after each operation, but a dash-pot 57 is con-' nected by an arm 58 to the sleeve 35 and prevents too forcible movement of the .sectors by cushioning their return. Suitable guides 59 are provided to hold the sectors against lateral movement. The platen 60 is common to both the add 12 ing and writingidepartments of the machine and is mounted in a suitable frame which travels upon a track consisting of two transverse rails 61. The said track is upheld by two vertical supports 62, Figs. 3 and 19 which are supported by the horizontal arms 63, whose front ends are rigid with a cross shaft. 64 located preferably near the base. One of said arms 63 is extended vertically in the form of a bell-crank (see Fig. 19) and the upper end thereof is connected by a link 65 to a vertical member 66 pivotally sup ported by the frame of the machine near the front end. i

The laten can be raised or lowered a short distance as required for writing purposes by means of two key levers provided for that purpose. The key lever 67 is pivoted near the rear end of the machine upon a rod 68-preferably near the left side-and carries a slotted cam member 69 Figs. 19 and 20 inclined downward toward the rear and terminating alongside of. the vertical member 66, which is provided with a lateral projection 7 9 which is drawn into the slot in the cam 69 whenever the key bar 67 is depressed. As is manifest, this operation results in elevatin the supports 62 and hence the platen (see ig. 19). Forlowering the platen a similar key bar 71 is provided and carries a forwardly depending slotted cam member 72 also adapted to receive the projection 70. Hence when the said key bar 71 is depressed the upper end of themember 66 is drawn rearwardly, the result being the lowering of the members 62 and the platen. The cam 69 controls the forward movement of the member 66 and the cam 72 itsrearward movement. The key rails are upheld by strong springs 73 and when in idle position the member 66 is stationary and held so by the projecting ends of the cams 69 and 72 and the platen will be held midway of its vertical movement which is its normal position.

The platen, however, 1s raised and lowered only for the writingdepartment and not at all when the adding department alone is used.

, A ribbon 74: extends across in front of the platen and winds upon spools 75, assing through guides 76 which are curve levers extending under the platen and having their rear ends rigid upon a rod 77 carried by the platen supports 62. The ribbon 74 is .normally held below the center of the front of the platen (see Fig. 7) in order to expose the record as printed, but whenever any record is made the ribbon is raised in order to receive the stroke of the type. For raising the ribbon the rod 78 is provided and has one end pivoted or otherwise connected to one ofthe guides 76' and its rear end supported by a projection 7 9 extending into a short horizontal-slot 80 in an 11 rightmember 81 pivoially supported by t 0 frame of the machine. Said rod 78 is adjustable as to length by means of a turn buckle of known construction. The ribbon is normally held downward by gravity but whenever the type carriers arc-operated said ribbon is raised,

the device for accomplishing this being the spring actuated bell-crank lever 82, Fig. 7 one arm of which rests against the rear side of a lateral projection on the rod 78 and the other arm of'which has a' projection 83 ex noearao parts are all in idle position as in Fig. 7, the lower arm of the lever 82 is held back by the arm 36,-but when the latter is lowered the lever 82 is moved by its spring, the lower arm of said lever pushing theprod 78 forward and thereby raising the front ends of the guides 78 which hold the ribbon. The ribbon is thereby brought to center of the front of the platen and is held there till the record is made and the type-carriers are returned to their former position, at which time the lever 82 is moved backward by the arm 36 and the guides 7 6 and the ribbon 74 are restored by gravity to their lowered positions.

For striking the types t8 against the platen when the type-carriers are raised, a

series of hammers Figs. 7 and lit-one for each type carrier-is mounted upon a shaft 85 supported transversely by the inner frames 18 in front of the sectors. The shaft 85 is rotatable and the hammers 8d are pivoted thereon and are actuated by springs 86 connecting them to same art 9f the frames. The hammers'are held own by pawls 87 mountedon a rod 88 and held vertically by springs 89 and arod 99. After each operation the hammers are restored to position by a rod 91 which is carried by two arms 92 rigid with the shaft 85, and rests under the rear ends of said hammers. Whenever the type-carriers are operated the rod 91 is low ered by means of a link 93 connecting one' of the arms 43 wit-h an arm9t attached to one end of the shaft 85 so that the latter will be rotated at every operation of the typecarriers. lit is manifest that the hammers will be restored to position by the rod 91 whenever the sectors and the link 50 move backward. An arm 95 is pivoted to each pawl 85, and said arms project rearward and rest upon the front ends of the levers 96 which are pivoted upon a shaft 97. The rear or lower ends of the levers 96 terminate adjacent to the lower edges of the type carriers 39 as shown, said sectors having shoulders 98 Fig.- 8 which lower the rear ends of the lovers 96 whenever the said sectors move forward farther than 0 position. Such operation raises the front end of the levers and thereby the ends of the arms 95, bringing the latter into the line of movement of the rod 91 which will push ,them forwardly and thereby release the pawls 87 from the hammers 84, the latter thereupon being thrown up by their springs 86 to strike the type and print 'hen the rod 91 is re turned to position the hammers are drawn back and again locked with the pawls 87.

Each arm 95 is provided with a projection 99 extending under its neighbor at the right so that when one of the series is raised all others at its right will be raised also, thereby permitting any of the Os to be tending over one of the arms 36 When the idle position after any number is registered by a pawl 100 .l ig. 8 carried by an arm 101 loose on the main shaft 52 alongside of an:- othcr arm 162 rigid on said shaft. A pin 103 on the upper end of the arm 102 extends. into a slot 101 in the arm 101 and hence will move the arm 101 when the main shaft is turned a suihcient distance. The pawl 100 is spring-actuated but is held down in opposition to its spring by a lug 105 in contact with one arm of said pawl and integral or rigid with some part adjacent to the pawl. l liowever, when the shaft 52 is operated the front end of the pawl is raised by its spring engages with a, pin 106 on the link 1? thus on the backward turning of the shaft 52 the link 17 and the bar 16 will also be moved, thereby turning the sector 11- a projection 107 rigid with the shaft 12. This results in turning the shaft 12 the gear sector 13 thereon forces the stop back and the upraised stops therein are lowered by the promotions 33. A certain lostmotion in the escapement member 25 permits the carriage to move a short distance leftward when the handle in the shaft 52 is released, in order a that the first row of pins may be moved upward again by the key bars without striking against the projections At the same time the pawl100 strikes against the lug 105 and is released from the pin 106 and the link 17 and the bar 16 are returned to their former positions by means of a spring (not shown) connecting the said link 17 to one of the adding machine or accumulator consists of a series of wheels 108'each with ten teeth representing the ten figures and normally in mesh with the gear sectors-or racks. Said vi heels are mounted on a shaft 109 supported by two plates 110, the front ends of which are pivoted to a rod 111.. The shaft 109 and the rear ends of the plates,110 are upheld by two supports 112 pivotally supported by the base of the machine and provided with curved or angular slots 113 within which. the ends of the shaft 109 rest. Normally the ends of the shaft are near the rear ends of the slots and when thus the wheels 108 are in mesh with the gear sectors or racks 36, but when the supports 112 are moved to the rear the shaft 109 will be lowered in the slots and the wheels 108 disengaged from the racks. A link 114 is pivoted to one of the supports 112 and the opposite or front end is upheld by a vertical link; 115 the lower end of the latter being sition when taking connected to the rear end of a bar 116. (See Fig. 8.) Said bar 116 is pivotally supported by one of the frames of the machine. The front end of the bar 116 is pivoted to the rear end of the total key bar 117. When the total key is lowered the rear end of the bar 116 is also lowered and this draws down the end of the link 11 1. Said link 11 1 abuts ,against a lug 118 on the frame and is thereby prevented from forward movement. A notch 119 is formed near the end of the link 114 and a pin 120 rigid with a small lever 121 rests in said notch. The lever 121 is rigid on a rotary pin 122 Fig. 3 supported by the frame and having on its outer end a bifurcated lever 123 also rigid therewith.

A lever 124 is pivotally mounted on the.

outer end of the pin 122 and carries a projection 125 which lies between the forks of the lever 123. The lowerend of the lever 12% is in the path of the movement of the segment 51 on the main shaft 52 and whensaid shaft is operated the segment thereon pushes forward the lower end of the lever 124 and thereby turns the pin 122. This results in the lever 121 pushing the link 11 1 rearward, which also pushes the supports 112 and draws the shaft 109 into the lower ends of the slots 113 and disconnects the wheels 108 from the racks 36. This occurs just before the racks start on their forward movement, so that the wheels 108 will not be disturbed. The continued forward movement of the segment 51 passes the same be-' yond the end of the lever 121, and then when the segment moves back to position the lever 124 is operated in the opposite direction and this draws the link 11 1 forward which operates the supports 112 and raises the wheels 108 into mesh with the gear sectors. This occurs just before the gear sectors start back, and hence their backward movement operates the wheels 108 to represent the number which had just been printed.

126 indicates the stop pawls or carrying levers which are pivotally mounted upon a rod 127 and which project toward the rear between the gear sectors 36. The rear ends of said pawls or levers are provided with hooks 128, the depth of which between the two arms is equal to one tooth on the sector or one tooth on the wheels 108. The sectors 36 are provided with pins 129 which strike against the ends of the hooks on the levers 126 and thereby stop the backward movement of the said sectors. On each wheel 108 except the one at the extreme left there is'a lug or shoulder 130 being on the O teeth of said wheels. Each lever 126 is provided with a shoulder 131 in front of said lugs 130 and forming sto s to stop the wheels in poa total. The lugs 130 project toward the left, the lug' on units wheel bearing against the pawl or lever 126 der the shoulder 131 and thus raises the heels 7 128 above the pin 129 on the gear sector in tens place and permits the sectorto be drawn bac by its spring until the pin 120 rests in the hook 128. This movement is equal to one tooth or digit and turns the totalizing wheel 108 in tens place a corresponding distance. Thus the carrying is accomplished trom a lower to a higher order.

The pawls or levers 126 are upheld by I pawls 132 pivoted on a rod 133 supported by the arms 134 which extend rearward under the wheels108. Said pawls 132 rest against shoulders 135 on the pawls or levers 126 and when one oil the latter is raised the pawl 132 is drawn under the shoulder 135 to uphold it, by means of a spring 136. However, when the wheels 108 are lowered the pawls 132 will be drawn to their normal osition by a rod 136' carried by the plates 10 and extending across over integral horizontal arms of the-pawls 132. This allows the pawls or levers 126 to return to their normal position and serve as stops for the sectors as above described. The arms 134 also carry a guide plate 137 on their rear ends, having a. series of projections 138 cm tlelnding between the gear sectors 36 to brace t cm.

is pivoted to an arm 140 integral with the bar 116 and the rear end is pivoted to a' 142 is also rigid on the shaft 23 and said levers carry a rod 143 at their upper ends. A slide 144 is supported by the plate s 'Z', 8 and is actuated rearward by means of a spring 145 and carries a roller 146 on its rear end which 0 crates against the rod 143 and from this it ollows that when the total key is lowered the slide will be pushed forward. This also lowers the stop 49 below the projections 38 by drawing downward the plate 146 by pins 147 on the slide which operate in inclined slots 148 in said plate 146. This allows the sectors to move torward to register the total except those which are not required, such sectors being held by the lugs 130 against the shoulders 131.

To print the total the total key is lowered which draws down the link 114 removing it from the pin 120 so that the shaft 52 can be operated by the handle 55, and the parts thereb operated without the link 114 being pushe' rearward. This leaves the wheels 108 in mesh with the gear sectors 36 and the 139 indicates a rod of which the non end intense latter will move forward and turn the wheels 108 until they are stopped by the lugs 130 striking against the shoulders 131 and such sectors as move will represent the total which will be printed in the manner set forth. The sectors not required to represent the total are held by the lugs 130 on the corresponding total wheels 108, bearing against the shoulders 131.

To repeat or reprint any number a number of times and in such cases to avoid striking the number on the hey hoard every time, it provide a repeating key 149 pivoted to a bell crank lever 150 supported at 151. The vertical arm of said lever carries a shield 152 which when the key 149 is operated passes under the projection 106 and prevents the pawl 100 from engaging therewith and therefore the bar 16 is not moved and the stop frame remains stationary and the same number can be printed any number of times or until the key 149 is released.

For correction in event of error on the part oil the operator in striking the keys, I provide an error key 153 pivotally mounted on the rod 111 adjacent to the link 17 and being in the form of a bell-crank and having a vertical arm 154 alongside of said link. The lower end oil said arm has a slot 155 formed therein and a pin 156 on the link 17 projects into said slot. The error key when lowered will draw the link 17 and the bar 16 rcarwardly and thereby restore the movable trame to its position at the right of the machine and thus the number therein repremnted is dissipated and the machine cleared from error, ready forwork again.

Having described the adding departmentoi. the machine and traced its operation, I will now describe the -writing department and explain how the two departments can be used together or separately as desired.

There is about the usual number of keys 157 and the bars oi these keys are located at the sides of the adding department one hall. at each side. Said bars are pivoted at the rear of the machine upon a shaft 158 and are operated by being struck in 'the' usual way, being u held by springs 159 located between said ars and a cross member 160. The type bars 161 in the form shown each comprise two arms, one being horizontal and the other being on an incline, thereby torming an acute angle the apex of machine. As may be clearly seen in Figs. 1"

and 5, the type bars are arranged in two
